 15. Added editable System settings with shared validation, a system update API, service/port conflict protection, and UI coverage for local save flows.
 16. Simplified the System tab layout by removing the redundant Runtime card and collapsing those fields into a compact settings section.
 17. Moved panel auth to server-issued expiring tokens with `sessionStorage` persistence and Compose-configurable credentials/TTL.
-18. Reworked Settings to store panel language/theme in `localStorage`, added RU/EN UI switching, and made service deletion warn before cascading linked-user removal.
